I have a customer that insists on a seasonal adjustment. They would like 30 degrees summer side of equinox and 50 degrees winter side. Wants to adjust twice a year at equinox. Rack to be 3 sets of 3 modules each on two rails. Every time I have tried this it is heavy and very difficult to do.

[RE-wrenches] module pricing
I'd like to do an unscientific poll and welcome any participants. Please to fill in the blanks. These two manufacturers are currently selling the highest priced PV modules at present (in terms of $/watt): _ and . I'll go first. SunPower and Sanyo. While there's been this pretty much manic race to the bottom as far as module pricing, I'm curious as to which manus are trying to make their stand on quality, high efficiency, power tolerance and premium pricing for an ostensible premium product.

It works pretty well: no penetrations or loading on the roof, still allows one bolt tilt adjust, azimuth to due south regardless of building orientation, etc. We normally would sit the pole in concrete, and then attach it with unistrut to the wall in a couple of spots. The unistrut would be long enough to catch 2 or 3 wall studs, and then attach to the pipe with a 6 unistrut clamp. As better roof mounting products have become available, we have been moving away from this method. Also, Grid tie just isn't near as critical for panel orientation, where as a small off-grid system in the winter really needs to be tilted to at least 30 deg, and within 20 deg of south to work right. Funny teaching us old off gridders to quit tilting, etc. with grid tie. Bill Brooks had some humorous examples of off grid sensibility applied in very ugly fashion to grid tie systems. At some point, I think NABCEP should consider separate certifications, as Off grid and grid tie have such different design requirements.

Re: [RE-wrenches] module pricing
MarcoTake a look in this months Home Power. There are many examples of mod manus and pricing to compare. Other websites that offer products point to the decline as well.One direction the manus seem to be taking is how to adjust to the commodity like fluctuations in pricing their products. It is a challenging environment for them now. When you consider that all of the 2009 manu capacity has been essentially pushed off the assembly line and only half of it has been sold, it puts tremendous pressure on them to turn inventory. The thinning of margins is hurting them and we could see some consolidation in the near future.My sense is this will be a cyclical thing and will sort it self out in the next 12-18 months as they regain pricing power as our economy stabilizes and confidence grows internationally.This is actually good for one subset of the market- the client. They are getting unprecedented deals that would have been unheard of two years ago, when we all were looking for product, but waited in line as the manus rumored to have shipped their products to higher margin places, like Spain that had robust FIT programs and pricing power.Time will tell whether micro cracks in cells and other maladays erupt in subsequent years for all and any manus. We should all hope for limited recalls. REC is doing it right, costing them a bunch, but this can happen in a hyper growth industry. Other manus might not have strong enough balance sheets to weather this type of storm and could be the Darwinian end to their operations as not having enough financial runway to sustain flight.AlohaKeithFrom: Marco Mangelsdorf ma...@pvthawaii.comTo: RE-wrenches re-wrenches@lists.re-wrenches.orgSent: Saturday, August 15, 2009 2:12:15 PMSubject: [RE-wrenches] module pricing I’d like to do an unscientific poll and welcome any participants.
